What is a .CGM file?

A .CGM file, which stands for Computer Graphics Metafile, is a type of image file that uses vector graphics. This format is particularly useful because it is designed to be compatible with a wide range of graphics applications. Initially, .CGM files were commonly used for storing clip art, but they have evolved to include more complex uses such as CAD (Computer-Aided Design) drawings. This evolution is due to updates in the ISO/IEC 8632 standard, which the .CGM format adheres to.

Vector graphics, like those used in .CGM files, are different from raster graphics because they use mathematical formulas to draw lines and shapes. This allows the images to be scaled (made larger or smaller) without losing quality, which is ideal for detailed designs and drawings used in engineering and architecture.

There are several programs that can open .CGM files, including: - IMSI TurboCAD Pro and IMSI TurboCAD Deluxe, which are professional CAD software. - Canvas GFX Canvas X Pro, a program designed for technical illustrations and graphics. - CorelDRAW Graphics Suite 2023, Corel PaintShop Pro 2023, and Corel Presentations 2021, which are comprehensive graphic design programs. - Autodesk AutoCAD 2023, a leading software in the field of CAD for professionals. - Adobe Illustrator 2023, a widely used graphic design tool that supports vector editing. - CADSoftTools ABViewer, which is a multi-functional viewer and converter for CAD files. - PTC Creo View Express, for viewing and annotating CAD models. - Larson Software Technology VizEx Reader, specialized in viewing technical documents. - IrfanView, a lightweight graphic viewer that supports a wide range of formats. - Apple AppleWorks, which was a multipurpose office suite but is now discontinued.

.CGM files can be encoded in three different ways: 1. Binary encoding: This is a standard method that allows the file to be read quickly and efficiently by software programs. 2. Character-based encoding: This method compresses the file to the smallest possible size, which helps save disk space and speeds up data transfer. 3. Clear-text encoding: This format is readable and editable with basic text editors, allowing users to see and modify the contents of the file directly.

Each encoding method serves different needs, depending on the user’s requirements for file size, readability, and ease of modification.
